There are lots of things that people do for hiccups. Most of the time I use cold ice water sipped slowly while holding my breath and constricting my diaphragm. Different people do different things but science has found that cold or ice on or around the front of the neck around where the Vegas Nerve is, does the best.

The hiccup is a nerve response and blocking that signal in that area is very helpful to get rid of them. Unless you have some sort of issue that requires doctor intervention, an ice pack placed below the jaw just off center to the left for a few minutes should help. Sometimes I just put a cold glass of ice water directly on my neck for a few seconds and that's all it takes.

I get hiccups in threes usually. When I get them they usually come back two more times that day, just milder. Mine can also be very violent, loud and painful.
